Amazon Product Description Guide: How to Write Descriptions That Convert
Learn how to write Amazon product descriptions that rank and convert. Covers HTML formatting, keyword placement, A+ Content, and common mistakes.
Why Amazon product descriptions matter
Most sellers underestimate the product description field. They copy-paste a few sentences from the manufacturer or write a generic paragraph that says nothing useful. Meanwhile, the sellers who dominate their category treat descriptions as a conversion tool, not a formality.
The product description appears below the bullet points on your listing. Customers who read it are often close to purchasing but need one more reason to commit. A good description answers objections, reinforces benefits, and creates a clear picture of what owning the product feels like.
HTML formatting in Amazon descriptions
Amazon allows a limited set of HTML tags in product descriptions. Use them to improve readability. The accepted tags include: paragraph tags for structure, break tags for line spacing, bold for key phrases, and italic for emphasis. Lists are not supported with HTML in descriptions, but you can simulate structure with bold headers followed by paragraph text.
Avoid unsupported tags. Amazon strips them and the result often looks broken. Always preview your listing after saving to confirm the formatting rendered correctly.
What to include in your description
A strong Amazon product description typically covers: the primary use case and who the product is for, a reinforcement of the two or three most important benefits (not all benefits, just the ones that drive purchase decisions), how the product solves a specific problem the buyer has, what makes this product better than alternatives (without naming competitors), and a brief statement on what is included in the package.
Keep it to 250 to 500 words. Longer descriptions lose readers. Every sentence should earn its place.
Keyword placement
Your most important secondary keywords should appear in the description if they are not already in your title or bullets. Amazon indexes descriptions for search. Do not keyword-stuff. Use keywords naturally in sentences that also make sense to human readers. A sentence like "durable camping lantern for hiking and backpacking" does the job without being jarring.
A+ Content replaces descriptions for brand-registered sellers
If you are enrolled in Amazon Brand Registry, A+ Content replaces the standard product description with a richer format: comparison charts, lifestyle images, enhanced text modules. A+ Content generally outperforms standard descriptions for conversion rate. If you qualify, use it. The standard description field becomes hidden when A+ Content is active.
Common mistakes to avoid
Describing features instead of benefits: "5000mAh battery" is a feature. "Lasts three days on a single charge during camping trips" is a benefit. Use both, but lead with the benefit. Writing in third person: "This product is great for..." reads as impersonal. Write directly to the buyer: "You get..." Another mistake is repeating exactly what the bullets already say. The description should add new information or context, not duplicate the bullets word for word.
Testing and improvement
Amazon does not A/B test descriptions natively for most sellers (Brand Analytics has some capabilities). Instead, track your conversion rate before and after making description changes. A conversion rate improvement of 1 to 2 percentage points on a high-volume listing can mean thousands in additional monthly revenue. Descriptions are worth the investment.
